Discussion:

After examining Ducke’s material (Brazil: Para, Peixeboi, Ducke 8798) and Amshoff’s (Suriname: Coppename R., Raleighfalls, Stahel & Gonggrijp 6300) as well as more recent exsiccatae, I have concluded that both authors were dealing with minor variants of the same species. Amshoff^19 was aware of Ducke’s work20 but distinguished D. pullei as having 7-9-pinnate leaves (instead of 4-5-pinnate) and the ovary with a few scattered hairs (instead of being densely hirsute). On the latter point there is in fact very little difference between the respective isotypes (NY), the disparity of description notwithstanding. The validity of the former distinction is lessened by the fact that a more recent collection from Para (Colonia 3 de Outubro, Pires, Black & Dobzhansky 4123), identified by Ducke as D. multiflora, has 8-jugate pinnae. Of the cited Amapa collections, first reports for that territory, 51386 has 7-jugate pinnae, 51613 5-jugate. The cited Suriname collection has 8-jugate pinnae. It should be further noted that on this last tree it was observed that there were leaves with pinnae numbering from 5 to 10, more or less according to the distance from the inflorescence.
